Area Forecast Discussion
National Weather Service Spokane WA
213 AM PDT Tue Apr 24 2018

.SYNOPSIS...
The Inland Northwest will experience high temperatures in the 70s
for the remainder of the work week. Some of our typically warm
lowland spots will have a shot of 80 degrees or more Thursday and
Friday. Cooler and showery weather will arrive over the weekend
and linger into early next week.

.DISCUSSION...

Today through Thursday night: High pressure aloft with a lower level
thermally induced area of low pressure to the southwest near the
coast remains in place in some shape or form into Thursday night. A
minor disturbance drops down and pushes the ridge back a bit on
Wednesday but the only effect expected by this will be a slight bump
up in north/northeast winds Wednesday, otherwise the general overall
trend of a dry forecast with a gradual warming trend with
temperatures on the warm side of what would be considered normal for
this time of year remains in place through this time interval.

Friday through Tuesday: Models are coming into better agreement on
the closed low that will affect our area this weekend. The GFS
continues to be the fastest model, but it has slowed a tad from
previous runs. This means that Friday`s temperatures will be
warmer than the previous forecast. Spokane may hit it`s first 80F
of the season.

I stayed away from the GFS idea of bringing rain into the area
Friday night, but held off until Saturday. Temperatures will be
cooler so the threat of thunderstorms is low, with the best chance
in the southern Panhandle. Sunday will be cooler still with the
best likelihood of rain. The easterly flow on the north side of
the low means that the Cascades could be rather wet. This coupled
with snowmelt could cause some rivers to approach or exceed flood
stage late in the weekend or early next week.

The low is very slow to move out of the area on Monday, and mainly
mountain showers will continue on Tuesday.  RJ
